Rule of Thumb: The rule of thumb safe working
depth of a bore from the surface and width from subsurface
utilities can be easily calculated. Multiply the tool's
diameter by 10 for proper depth from the surface and
by 4 for the safe width (lateral distance) subsurface
obstructions. |

| 12 models of Grundomat piercing tools
are available in diameters ranging from 1 3/4 inches to 7 inches.

Pipe Extraction
The Grundomat is also easily configured
for pipe pushing (extraction) applications. During pipe extraction,
a pipe-pushing adapter is placed on the front of the piercing
tool. The tool's percussive force is then used to literally
drive out an existing service line. |
Pipe Pulling
The Grundomat can also be easily configured
for pipe pulling applications. Several pipe pulling clamps and
adapters are available for pulling a wide variety of pipes including
PVC, HDPE, copper and steel. |
